Problems solved by technology
However, its construction is very complex and can suffer from low efficiency and reliability, high vibration levels and heavy weight
[0006] Another problem affecting known tilting solutions relates to the fact that these solutions are unsatisfactory when applied to steered wheels; in particular, in known solutions, the steering or tilting angles are very limited and there are no good known solutions that enable Good performance in both steering and tilt functions
In particular, this is due to the fact that the standard ball joint types used for car suspensions cannot be used at high lean angles
In fact, the ball joints used in the car are designed to rotate freely about the steering axis, but their tilt angle is limited to less than 40°
However, such a tilt angle is not suitable for a large tilt suspension system when the turning angle is required to reach 100°

A tilting suspension system is provided for two wheels of a vehicle disposed on a common axle with said module comprising a rigid frame adapted to be firmly fixed to the chassis of the vehicle so as to be tilted together with the whole vehicle. The tilting of the rigid frame is obtained as a result of the counter torque arising when activating actuating means firmly fixed to the rigid frame, with said tilting means being pivotable connected to shock absorbers 18. The tilting module further comprises suspension arms usually connected to the rigid frame, with said suspension arms supporting, in cooperation with supporting uprights, the two wheels thus allowing both tilting and steering of said two wheels. Moreover, electric motors may be received in the hubs of the wheels, thus allowing the realization of driving, steering and tilting module adapted to be used either in hybrid vehicles or electrically driven vehicles.
Description
technical field [0001] The invention relates to the field of automobile applications, in particular, the invention relates to a suspension tilting module of a wheeled vehicle and a wheeled vehicle equipped with the suspension tilting module. More specifically, the present invention relates to at least two wheels that enable a coaxial arrangement of a vehicle and a suspension tilting module that enables said two wheels to tilt together with the entire vehicle body. More specifically, the present invention relates to a suspension tilt module enabling steering and tilting of said two wheels. Moreover, the present invention relates to a drive motor housed at the hubs of two coaxially arranged wheels for realizing a suspension tilting module that actively controls the torque of the coaxial wheels, for example, increasing the torque of one wheel and decreasing the torque of the other wheel. Background technique [0002] Over the past few years, due to the growth in the number of ...
